B_s(d) - bar B_s(d) mixing constraints on flavor changing decays of t and b quarks

Amand Faessler, Thomas Gutsche, Sergey Kovalenko +2

We study those dimension 6 effective operators which generate flavor-changing quark-gluon transitions of the third generation quarks, with t -> g + u(c) and b -> g + d(s), and whic…
